Computational Fluid Dynamics
OverviewSTAR-CCM+ is CD-adapco´s newest CFD software product. It uses the well established CFD solver technologies available in STAR-CD, and it employs a new client-server architecture and object oriented user interface to provide a highly integrated and powerful CFD analysis environment to users. This environment includes advanced pre and post-processing tools, including CAD import geometry surface analysis, automated surface repair, tools for identification and hand repair of small numbers of surface defects, tunable surface wrapping to retain the amount of surface detail required for CFD analysis, advanced automated meshing that yields polyhedral, hexahedral, or tetrahedral volume meshes, pre-simulation post processing visualization setup that can be used to monitor the progress of a simulation during solution, and a variety of other tools to ease the work of CFD analysts, such as the ability to copy and paste model components between models.
With its new graphical user interface including many automated tools for meshing, solution monitoring, and post processing visualization, and plotting of primary variables and derived quantities, STAR-CCM+ is one of the easiest full featured CFD software packages to learn.
The STAR-CCM+ license allows an unlimited number of concurrent jobs, and they can use all of the available processors and cores.
Current TRACC ApplicationsTRACC, Turner-Fairbank Highway Research Center (TFHRC), and researchers at the University of Nebraska and Northern Illinois University are collaborating on the study of CFD-based simulation techniques. Researchers are taking reduced-scale experiments from the TFHRC hydraulics laboratory, providing the data for CFD model development, and producing a validated CFD-based advanced simulation methodology for open-channel flow, with an emphasis on riverbed scouring under bridges and the evaluation of lift and drag forces on bridge structures during floods.
The applicability of commercial CFD codes such as STAR-CD for prediction of these phenomena is being investigated, and the agreement between the code predictions and experimental data will be determined for various modeling options. The scalability of these simulations to large numbers of processors, particularly for the simulation of full-scale bridge deck interactions, is being evaluated and guidelines will be developed for the decomposition of problems of this type. Cross-code comparisons of the calculated results to evaluate computational efficiency and accuracy are also under investigation.
